大家！我可以请您帮我解码以下JSON代码：

$json = '{"inbox":[{"from":"55512351","date":"29\/03\/2010","time":"21:24:10","utcOffsetSeconds":3600,"recipients":[{"address":"55512351","name":"55512351","deliveryStatus":"notRequested"}],"body":"This is message text."},{"from":"55512351","date":"29\/03\/2010","time":"21:24:12","utcOffsetSeconds":3600,"recipients":[{"address":"55512351","name":"55512351","deliveryStatus":"notRequested"}],"body":"This is message text."},{"from":"55512351","date":"29\/03\/2010","time":"21:24:13","utcOffsetSeconds":3600,"recipients":[{"address":"55512351","name":"55512351","deliveryStatus":"notRequested"}],"body":"This is message text."},{"from":"55512351","date":"29\/03\/2010","time":"21:24:13","utcOffsetSeconds":3600,"recipients":[{"address":"55512351","name":"55512351","deliveryStatus":"notRequested"}],"body":"This is message text."}]}';

我想将上述结构组织为：

回答：

文件夹：收件箱

来自（来自）：…

日期（日期）：…

时间（时间）：…

utcOffsetSeconds：…

收件人（地址）：…

收件人（姓名）：…

状态（deliveryStatus）：…

文字（正文）：…

您可以使用该json_decode函数来解码JSON字符串：

$json = '{"inbox":[{"from":"55512351","date":"29\/03\/2010","time":"21:24:10","utcOffsetSeconds":3600,"recipients":[{"address":"55512351","name":"55512351","deliveryStatus":"notRequested"}],"body":"This is message text."},{"from":"55512351","date":"29\/03\/2010","time":"21:24:12","utcOffsetSeconds":3600,"recipients":[{"address":"55512351","name":"55512351","deliveryStatus":"notRequested"}],"body":"This is message text."},{"from":"55512351","date":"29\/03\/2010","time":"21:24:13","utcOffsetSeconds":3600,"recipients":[{"address":"55512351","name":"55512351","deliveryStatus":"notRequested"}],"body":"This is message text."},{"from":"55512351","date":"29\/03\/2010","time":"21:24:13","utcOffsetSeconds":3600,"recipients":[{"address":"55512351","name":"55512351","deliveryStatus":"notRequested"}],"body":"This is message text."}]}';
$data = json_decode($json);
var_dump($data);

而且您会得到像这样的东西：

object(stdClass)[1]
  public 'inbox' => 
    array
      0 => 
        object(stdClass)[2]
          public 'from' => string '55512351' (length=8)
          public 'date' => string '29/03/2010' (length=10)
          public 'time' => string '21:24:10' (length=8)
          public 'utcOffsetSeconds' => int 3600
          public 'recipients' => 
            array
              0 => 
                object(stdClass)[3]
                  public 'address' => string '55512351' (length=8)
                  public 'name' => string '55512351' (length=8)
                  public 'deliveryStatus' => string 'notRequested' (length=12)
          public 'body' => string 'This is message text.' (length=21)
      1 => 
        object(stdClass)[4]
          public 'from' => string '55512351' (length=8)
          public 'date' => string '29/03/2010' (length=10)
          public 'time' => string '21:24:12' (length=8)
          public 'utcOffsetSeconds' => int 3600
          public 'recipients' => 
            array
              0 => 
                object(stdClass)[5]
                  public 'address' => string '55512351' (length=8)
                  public 'name' => string '55512351' (length=8)
                  public 'deliveryStatus' => string 'notRequested' (length=12)
          public 'body' => string 'This is message text.' (length=21)
      ....
      ....

既然您知道了数据的结构，就可以对其进行遍历；例如，您可以使用以下内容：

foreach ($data->inbox as $note) {
  echo '<p>';
  echo 'From : ' . htmlspecialchars($note->from) . '<br />';
  echo 'Date : ' . htmlspecialchars($note->date) . '<br />';
  echo 'Body : ' . htmlspecialchars($note->body) . '<br />';
  echo '</p>';
}

这样您将获得以下输出：

From : 55512351
Date : 29/03/2010
Body : This is message text.
From : 55512351
Date : 29/03/2010
Body : This is message text.
...
...
